LG Display has a prototype 18-inch screen that rolls up like a piece of paper

LG Display has a prototype 18-inch screen it's showing off at the Consumer Electronics Show this week that rolls up like a piece of paper. The technology builds on LG's forward-looking OLED work focusing on bendable, rollable, and curving displays. The company showed similar technology last year as a proof of concept, but kept images behind closed doors. Now LG looks ready to show the world.
